In a laboratory study, treatment of dye wastewater having high chemical oxygen demand (COD) in the range of 9000 to
10000 mg/L. by sonolysis was examined. Batch experiments were conducted to determine optimal sonolysis time (with and
without dipping) to obtain the best results. In the present work, degradation of pharmaceutical effluent has been investigated using
acoustic cavitation process. In this study, the effect of acoustic cavitation was examined for the different time intervals from 0 to
90 mins. In acoustic cavitation high frequency probe was used of 20 KHz capacity and reactor capacity was 1 liter. With acoustic
cavitation, maximum COD removal achieved was 75.53% in 75 mins.
